OK then. What nameserver daemon behaves like this?
various versions of IE cache either for 30 minutes or an hour irrespective of the times they get back from the resolver. see http://support.microsoft.com/default.aspx?kbid=263558 I believe gecko based browsers are guilty of this too (although to a lesser extent -- 10 minutes iirc).
Well, guilty is a bit too harsh word. This is done to prevent DNS rebinding attacks. All browser do this btw, though for (of course) different time intervals. Cheers, Bojan
